Abstract

Disclosed are a negative electrode plate, an electrochemical energy storage apparatus and an electronic apparatus comprising the negative electrode plate. A negative electrode active material of the negative electrode plate includes a first amorphous carbon material. An interlayer spacing d002 of the first amorphous carbon material is greater than 0.34 nm, and an average pore diameter of pores of the first amorphous carbon material ranges from 2 nm to 20 nm. The negative electrode plate can help improve energy density of a lithium-ion battery and suppress expansion of an electrochemical energy storage apparatus during cycling.
